Prasophyllum regium
King leek orchid is a tall, deciduous terrestrial orchid from south-west Western Australia, grown mainly by enthusiasts and native-plant collectors rather than as a common houseplant. It grows from an underground tuber and needs cool, moist winters with a dormant summer.
Prasophyllum regium, commonly known as the king leek orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single, unusually thick tubular leaf and up to one hundred relatively large, greenish-brown or burgundy-coloured flowers. It is one of the tallest leek orchids, sometimes growing to a height of 2 m (7 ft).
The king leek orchid is found between Perth and Albany in the Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions, growing in a wide range of habitats from seasonal swamps to dense forests.
